How to remove grub from a GPT hard drive?

I once installed Debian onto my hard drive with GPT so there is a grub on it. Recently I erased Debian for some reason. But the grub is still there (which can launch nothing). How can I remove it? I know the trick

Code:

---

dd if=/dev/null of=/dev/sdX bs=446 count=1

---

for MBR, can it be applied to GPT? Thank you.

If GRUB is sitting on physical partition which is not used by other OS, storage, etc. you can format the partition using utility of your choice (like Gparted !)

Hello and welcome! :)

In addition to what Shantanu said above, installing a different bootloader to the same locations should overwrite GRUB, thereby removing it.
